Specification of Letters Patent. Patented Jluly 20, 1915.

Application filed May 21, 1914. Serial No. 840,056. l

i7 10 all whom it may concern Be it known that I, .loi-1N B. NAINTEAU, acitizen of the United States, residing at Pawtucket, in the county ofProvidence, State of Rhode Island, have invented certain new and usefulImprovements in Spindles; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to spinning frames and has special reference tomountings or bearings for the spindles used in such frames.

In the usual spindle mountings oiling is accomplished through an openhole or tube and the amount of oil suppliedy at one time is therebynecessarily limited. Furthermore, dust and foreign substances can enterthe usual oil hole and they not only-tend to clog the oil passages butalso to injure the spindle.

Another disadvantage incident to the spindle mountings with which I amacquainted, is that under the rapid rotation of the spindle, the oilwhich has been fed into the space between the usual bolster and thespindle will climb o-r work its way up the spindle to a point above thespindle mounting, thence dropping or flowing down on top of the mountingso that, not only is the upper exterior portion of the spindle coatedwithvoil, but the ymountingis likewise exteriorly so coated, andconsequently the band or belt passing around the whirl is liable to besoiled, as is also the arm itself. Furthermore, in the ordinary type ofspindle mounting there is employed a tongue or catch which is located atone side of and projects over the top of the whirl, this catch or tonguebeing usually mounted on toprof the oil chamber. AThe result is `that itis in the way of the band or belt which passes around the wheel, and asthe belt in its travel is liable to flap' orwabble, it strikes against`this catch or .tongue and consequently is rapidly worn out, so that itis frequently broken.

To obviate the above recited disadvantages incident to the ordinary typeof spindle, I propose to provide an oil baliiing member,which is carriedby the yspindle and is located in a small chamber or space between thetop of a sleeve surrounding the bolster, so that, as the oil works upthespindle it will strike this baffle and be deflected downward into thevchamber. In other words, by means' of this baille, located in suchchamber aforesaid, the oil is prevented working up the spindle above thespindle mounting. I also prevent the wearing or injuringl of the band orbelt passing over the whirl bylocating 'the oil chamber below the whirland providing the latter with a cover or top which is devoid, of allhooks, clips,- tongues or other projections, which are liableto catch orcontact with `the belt or` band passing over the whirl.

.Another object of the invention is to provide an improved spindlemounting wherein the oil will be kept in a suitabley reservoir or cupsothat it may at ally times be supplied to the spindle. V

Acfurther object of the invention is to provide an improvedvadjustment-for such spindlesv wherein the spindle may be adjusted andthe oil baffling member of the spindle properly located relative totheannular inturned flange at `the top ofthe/sleeve surrounding thespindle without making it necessary to stop the machine. I

With the above and other objectsfinlview the invention consists. in.general of. certain n ovel details of construction'l and combina,- tionof parts hereinafter *fully described,

illustrated in the accompanying drawings,

and 'specifically claimed;

In the accompanying chine showing a spindle mounting constructudraw-ings', ylike characters of reference indicate like` partsin the.-

Fig. 5 is a bottom view of said cap. Fig. 6is a detail sidek elevation of the spindle bolster. Fig. 7 is a detailside elevation of the spindle adjusting nut. Fig. 8 is a plan view of alock nut used herewith. Fig. 9 is a transverse section through said nut.Fig. 10 is an enlarged detail view of a stop pin used herewith. Incarrying out* the objects of-this invention there is provided the usualspindle l having the tapering' upper end 2 4and the tapering lower end3, the flatter v.constituting the cone foot step bearing for` the spin,-dle. I rictionally engaged upon the spindle is a sleeve 4, whereon isformed a whirl 5 of the usual type and by means of which the spindle isrotated. Mounted upon said sleeve 4 is a bobbin holding device 6. All ofthe foregoing parts are preferably of any one of the standard commercialtypes.

lt is to be understood that the usual seriesh of spindles are employedand that the machine is equipped with the usual spindle rail S. For eachof the spindles in the machine there is provided a sleeve 7 which is setinto the spindle rail as at 7 and is locked in position in the rail by asuitable nut 7 u. Each of these sleeves is provided immediately abovethe threaded portion with a cylindrical portion 9 and below thisthreaded portion is a second reduced cylindrical portion 11.lntermediate the length of the spindle and positioned above the rail isa cup 12 which surrounds said sleeve and thus forms an annular oilreceiving chamber. T he upper end of the sleeve is preferably of lessdiameter than the portion 9 and eX- tends upward above the cup asindicated at 13. rlhe interior 14 of this portion of the sleeve islikewise of less dia-meter than the interior 15 of the central portionof said sleeve while the lower end of the sleeve has an opening thereinreduced and threaded as at 16. rlhe upper end of said sleeve has itsopening kalso reduced and threaded as at 17. Extending from an annularchamber formed by the cup 12 and communicating with the interior 15ofsaid sleeve is a plurality of oil ports 18. The cup 12 is likewiseprovided, near its upper edge with a lateral oil port 19. Beneath theoil port 19 the cup is provided with a threaded recess 20 and oppositesaid recess the wall of the cup is bored to provide a vertical recess21. Slidable in the vertical recess 21 is a pin 22 provided with aconical point 22 and beneath the lower end of this pin is a spring 23which urges the pin upward. The cua 12 is preferably filled with fibrousmateria l as indicated at 24.

Mounted on the cup 12 is the cap 26 having in its top 27 an opening 28to receive the sleeve 7. This cap is likewise provided with an oil port29 which may be caused to register with the port 19 by rotation of thecap on the cup and in order to limit the amount of such rotation the capis provided with a peripheral slot 30 which registers with the recess20, a screw 32 passing through said slot and engaging the recess so thatthe cap may be turned to a certain eX- tent in either direction while7at the same time, it cannot be removed from the cup without unscrewingthe screw 32. The top of this cap is also provided on its under sidethese ports out of registry. In connection reduced as at 36 and theportions 35 and 3G are provided with a suitable opening or bore 37wherein the end 3 of the spindle fits closely. rlhe lower end of thisbolster is enlarged and threaded as at 38 so that it engages thethreaded portion 16 of the sleeve 7 and this lower end is provided witha cylindrical bore 39 for purpose hereinafter to be described. Suitablescrew driver slots are also provided in this bolster and oil ports 41extending laterally through the central portion of said bolster. At 43is shown the adjusting screw which carries a cylindrical boss 44 formingthe foot step bearing for the spindle and this screw is also threadedinto the portion 16 of the sleeve 7, being provided with a screw driverslot for the purpose of adjustment. At 47 is shown a lock nut for theadjusting screw and this lock nut is provided with the spanner hole 48and the threads 49 to enga ge the c threaded portion of the screw 43.

In oiling the device', which may be done while the machine is running,the cap is turned until the ports 19 and 29 are in registry. The nozzleof the oiler is inserted and the cup filled with oil. This oil will passout through the port 18 and port 41 to the spindle end 3. The adjustmentof the device may also be done while the machine is running by looseningthe lock nut 47 and turning the screw 43 to the right or left asdesired.

By reference to Fig. 1 it will be seen that the upper end of the sleeveis formed with an annular inturned flange producing a reduced threadedopening or bore 17 hereinbefore mentioned, and as this flange, which isindicated at 17 lies spaced from the upper end of the bolster, a smallchamberl is produced by the flange 17', the top end of the bolster andthe portion of the wall of the sleeve lying between the bolster and theflange. The spindle is provided with a collar having internal screwthreads running in the same direction as the threads of the flange 17 sothat in setting the spindle in operative position the collar may bescrewed through the bore 17 at the top of the sleeve until it Alieswithin the chamber formed as aforesaid. This collar performs animportant two-fold function. Not only does it prevent the accidentaldisengagement of the spindle or its bearing, that is to say prevents thespindle from jumping upwarrh but primarily it acts as an oil baille. Theoil as it is supplied from the oil cup or receptacle, passes through theoil ports or passages 18 to the space between the sleeve and bolster ofthe `spindle and thence throi'lgh the port 41 to the spindle. ln therapid rotation of the spindle the oil will -'climb or j travel upwardlthereon, and were it not for this battling collar 55, such oil wouldcontinue it way up the spindle to the eXterior of the complete housing,and would notonly coat the upper portion of the spindle, lbut` wouldoverflow onV the housing and consef quently `would not only collect dirtand grit, thus soiling the parts, but would be liable to soil the beltspassing over the whirls, and also in some cases' soil the yarn, as smallparticles of oil would be liable to be thrown off in the rapid rotationof the spindle. With my construction, however, it is impossible for 4theoil to escape: to the exterior of the Ahousing and to coat the upperportion of the spindle, for it has been foundin actual use that the oilwill be confined within the licusy ing and will not escape therefrom, asis the case vwith ordinary spindle housings with which I am acquainted.Thus, I not only save the oil, and maintain the spindle and its bearingsin a comparatively clean state, but I also avoid the liability ofsoiling the work and the belts or bands of the whirls. It will be notedthat while the collar may be screwed through the bore of the flange atthe top of the sleeve to bring'it within the chamber, such collar willprevent the .upward movement of the spindle and the accidental removalof the'same from the sleeve, as the spindle can only be removed byunscrewing the collar through" the threaded bore 17. There has thus beenprovidedl a simple and efficient device of the kind described and ofthecharacter specied.

It will be obvious that many minor changes may be made in the forni andconstruction of this ini ention withou departing from the materialprinciplestliereof. It is not therefore desired to confine the inventionto the eXact form herein shown and described, but it is wished toinclude all such as come properly within the scope claimed.

' It will also be observed that this prevents this spindle from beingwithdrawn during dofling of the bobbins.

Having thus described the invention, what is claimed as new, is
